Two-Step Equations

Coefficient

Constant

Two Step EquationsTwo Step Equations

Two-Step Equations are equations that require two-steps to solve.You will ADD or SUBTRACT and then

MULTIPLY or DIVIDE.

33xx + 8 = 29 + 8 = 29

CoefficientCoefficient

Coefficient – The number that is attached to a variable

33xx + 8 = 29 + 8 = 29CoefficientCoefficient

CoefficientCoefficient

To get rid of the coefficient, you will either MULTIPY or DIVIDE

ConstantConstant

The constant is the number that is not attached to a variable.It MUST be on the same side of the equal sign

as the variable.

33xx + + 88 = 29 = 29CoefficientCoefficient ConstantConstant

ConstantConstant

To get rid of the constant, you will either ADD or SUBTRACT

You get rid of the constant FIRST!!

4x + 12 = 20

6x + 3 = 154

-17x + 2 = -8

5x + 15 = 24 -7x - 11 = 33

4x - 13 = -63

-8x + -12 = -20

Label the Coefficient and the Label the Coefficient and the ConstantConstant

How do I solve two-step equations?How do I solve two-step equations?

To solve two-step equations, you do order of operations in REVERSE

This means that you do addition or subtraction FIRST

Reverse order of Reverse order of operations? What does operations? What does

that mean? Isn’t there an that mean? Isn’t there an easier way to understand easier way to understand

Which number do I “get rid of” first?

What operation do I do?

What number do I “get rid of” next?


3x - 5 = 73x - 5 = 7






6x + 12 = 246x + 12 = 24






-2x - 4 = 10-2x - 4 = 10




2x + 4 = -102x + 4 = -10






-5x + 12 = 32-5x + 12 = 32





-3x + 6 = 27-3x + 6 = 27






-9x + 9 = -18-9x + 9 = -18





6x + 12 = 186x + 12 = 18


5x - 15 = 205x - 15 = 20


-8x + 10 = 42-8x + 10 = 42


-15x - 5 = 40-15x - 5 = 40
